description: Set up components for custom environments like iframes, Shadow DOM, or Electron.

## Motivation

We use [Zag.js](https://zagjs.com/overview/composition#custom-window-environment) internally, which relies on DOM query
methods like `document.querySelectorAll` and `document.getElementById`. In custom environments like iframes, Shadow DOM,
or Electron, these methods might not work as expected.

To handle this, Ark UI includes the `EnvironmentProvider`, allowing you to set the appropriate root node or document,
ensuring correct DOM queries.

## Setup

To support custom environments like an iframe, Shadow DOM or Electron, render the `EnvironmentProvider` component to
provide the environment context to all Ark UI components.

<Example id="setup" />

### Usage in iframe

The `EnvironmentProvider` component will automatically detect the current environment and set the correct environment
context. However, you can also manually set the `Document` like shown in this React example below:

```jsx
import Frame, { FrameContextConsumer } from 'react-frame-component'
import { EnvironmentProvider } from '@ark-ui/react'

export const App = () => (
  <Frame title="IFrame Context">
    <FrameContextConsumer>
      {({ document }) => <EnvironmentProvider value={document}>{/* Your App */}</EnvironmentProvider>}
    </FrameContextConsumer>
  </Frame>
)
```

### Usage in Shadow DOM

Here's an example of how to set the `EnvironmentProvider`'s value with Shadow DOM in Solid.js `Portal` component.

```jsx
import { EnvironmentProvider } from '@ark-ui/react'
import { Index, Portal } from 'solid-js/web'

export const App = () => {
  let portalNode
  return (
    <Portal ref={portalNode} useShadow={true}>
      <EnvironmentProvider value={() => portalNode?.shadowRoot ?? document}>{/* Your App */}</EnvironmentProvider>
    </Portal>
  )
}
```

## Context

Use the `useEnvironmentContext` hook to access the `RootNode`, `Document`, and `Window`.
